Using of Detergent in Indonesia
For other cleaning materials, detergents is the yield of technological advances that make use of the chemical byproduct of petroleum distillation, combined with other chemicals such as phosphate, silicate, dye, and fragrance ingredients. around in the 1960s, the early generations detergent appeared using surface pengaktif chemicals (surfactants) Alkyl Benzene Sulfonat (ABS) is capable of producing foam. However, due to the difficult nature of ABS broken down by microorganisms in the soil surface, eventually replaced by Linear Alkyl compounds Sulfonat (LAS) are believed to be relatively more familiar with the environment.
In many countries in the world have banned the use of ABS and replaced with the LAS. While in Indonesia, the regulations concerning the prohibition of using ABS does not exist. Several reasons ABS is used in detergent products, such as low cost, stability in the form of cream / pasta and abundant foam.
